Description
1. Product Overview
Gel Blocking Agent — Water Shutoff is a high-performance polymer-based chemical system engineered for selective water control in oil & gas reservoirs. Its primary industrial use is to reduce excessive water production in mature wells by forming a strong, durable gel barrier that blocks water channels while maintaining hydrocarbon flow. The key value proposition is significant OPEX reduction and improved oil recovery through targeted water shutoff, with field-proven success rates exceeding 85%. Strategically, this technology addresses the $45B global produced water management market, enabling operators to extend well life, meet environmental compliance targets, and maximize asset profitability.

3. Core Industrial Applications
- Primary Industries: Upstream Oil & Gas, Enhanced Oil Recovery (EOR), Geothermal Energy, Underground Gas Storage
- Specific Operational Use Cases:
- Water Shutoff in Production Wells: Selective plugging of high-permeability water zones, fractures, and channels in sandstone and carbonate formations
- Conformance Control: Profile modification for waterflood and polymer flood projects to improve sweep efficiency
- Casing Leak Remediation: External sealant for micro-annuli and cement sheath failures
- Gas Well Dehydration: Mitigate water loading in gas wells to sustain production rates
- Performance Advantages vs Alternatives: Unlike cement squeezes or mechanical plugs, this gel system penetrates deep into the matrix and selectively bonds to water-wet rock. It offers superior injectivity, controllable gelation time from 4 hours to 7 days, and post-treatment permeability regain for oil. Delivers 40-60% lower treatment cost and 3x longer effective life compared to conventional silicate gels
